If It can help you... I asked about adding strikes you like Cross/Star shaped bloom.As i remember, there is parameter as global constant which define pass number, it may allow to switch between processing to keep standart bloom for lower resolution textures and strikes for more detailed[...] TempParameters.w is pass [...] you can add more passes in techniques, just use additive mix or smoother blending. the problem only to separate result. but not a big problem if to apply it for first pass of bigger bloom texture only, compute in it that strike effect completely and in all other passes use as source prepass result of that one with strikes, but the side of it (compute left with bloom, right with strikes)
Said that the version must be reprogrammed to support palette on other files.
btw, uploading my bloom on the forum now; I need external help (screenfact/tempparams) for smoothing.
